Number

From Conservapedia

A number is a term that describes the amount of something and is used for counting of measuring.

Numbers are usually represented in English writing by a system of numerals:

0 (zero)

1 (one)

2 (two)

3 (three)

4 (four)

5 (five)

6 (six)

7 (seven)

8 (eight)

9 (nine)

Which can be used in combination to represent any number of any size. An older system of representation, still sometime encountered on clocks and other places, is Roman numerals, which used certain letters of the alphabet instead.
